Description
【考案の詳細な説明】 （産業上の利用分野） この考案は注射針に関する。[Detailed explanation of the idea] (Industrial application field) This invention relates to a hypodermic needle.
（従来の技術）
従来、注射器は薬液を注射筒に吸引し、注射針

液が残留し、無駄になつていた。また、注射針の
針基にも薬液が残留し無駄になつていた。(Prior art) Conventionally, a syringe draws a medicinal liquid into a syringe barrel and injects it into the patient's body from the tip of the needle. The gasket did not arrive, and some of the chemical solution remained and wasted. In addition, the drug solution remained on the base of the injection needle, resulting in waste.
（考案が解決しようとする問題点）
そこでこの考案は上記の欠点を除去し、薬液が
無駄にならない注射針を提供するものである。(Problems to be Solved by the Invention) This invention therefore eliminates the above-mentioned drawbacks and provides an injection needle in which no medicinal liquid is wasted.
（問題点を解決するための手段）

より構成される。(Means for Solving the Problems) An embodiment of this invention will be described below with reference to the drawings. In the injection needle 2 attached to the syringe barrel 1,
The needle base 2a of the injection needle 2 is made of a slightly elastic material such as synthetic rubber or synthetic resin, and is used to connect and fix the injection needle to the syringe barrel 1 and to fill the dead volume of the tip 1a of the syringe barrel 1. The needle base of the injection needle is inserted into the tip of the syringe barrel and is provided with a stop member 4 for fixing the needle base.
尚、差込み部材３の断面は、差込みを容易に

る。(Function) Next, to describe how to use this device, insert the insert member 3 attached to the injection needle 2 through the tip 1a of the syringe barrel 1, fill the inside of the tip 1a with the insert member 3, and stop. The member 4 is attached to the tip 1.
After fixing the injection needle 2 to the syringe barrel 1 by inserting it into the hole a,
The medicinal liquid is sucked into the syringe barrel 1 and used.
（考案の効果）
この考案によると、注射針の針基部１ａに設け

積を存せず、薬液を無駄にしないため、薬液を効
率よく使用出来、極めて有益なる効果を奏する。(Effect of the invention) According to this invention, the tip 1 of the syringe barrel 1 is
Since the inside of a is filled with the deforming member 3, this part does not become a dead volume unlike in the past, and the injection needle itself does not have any extra internal volume other than the drug solution passage, so the drug solution is wasted. Because it does not cause any damage, the chemical solution can be used efficiently and has extremely beneficial effects.
